The screen has the same 1.39 inches from Gen2 M45, so the advantage is just the better resolution (326ppi Gen3 vs 287ppi Gen2 M45). BTW, Gen2 M41 is also 326ppi like Gen3, in a -obviously smaller- 390x390 screen.
But both M45 and M41 have AMOLED screen, which is supposedly better (and more expensive) than the just OLED Gen3 screen, so the screen advantage is then not so relevant
So from your answer I understand there’s no Always On Display difference between Gen3 and Gen2, except for a better resolution vs M45 (not vs M41)
About the Autavia and Monaco watchfaces on the Connected... yes, you are right, the TH Connected (mostly Gen1 and Gen2, with direct Carrera 45mm design) is in fact a Carrera Connected, so being purists, we only should wear Carrera watchfaces... but on the other hand, as only Carrera Connected exists and there are no Monaco Connected, Autavia Connected... I think the all three Gen of THC are legitimated to wear any TH/Heuer face, just for fun
😀
But here some pictures with Carrera watchfaces (AOD on, dimmed mode) for our pace of mind
